To all'whojm itmay concern: I

Be it known that we, OT'ro C. HOFFMAN and JOHN J. DUNN citiZens of the United States, residing at Buffalo, in the county.

-- Contents of Paper Cups,.of which. the following is a specification, reference being had to the accompanying drawings, in which similar numerals of'reference indicate corresponding parts in the several views.

This invention relates to machines for emptying paper cups of their contents and more particularly to removing ice cream from paper .cups. V

The principal Object of the invention 1s to provide a simple means of removing the contents of a paper cup by forcing the bottom of said cup through the top and there- ,by carrying the contents of said cup'with the said bottom. Another object is to furnishnieans for supporting said cup by its rim and in an inverted position wherebythe contents of said cup when forced out may be caught by areceptacle held beneath said cup. Another object is to furnish means to carry and raise'a'loaded and inverted cup up against a stationary disk toremove the v contents of said cup and whereby the weight of said carrying means will return it to the' I V j of clearance when raised to 11 111 Fig. 1.,

starting position when released.

With these objects in view, the invention consists incertain features of novelty in the construction, combination and arrangement of parts by which the said object and certain other objects which will hereinafter appear are attained,- the invention being more particularly pointed out in the claims. H In the drawings, Figure l is a vertical side elevation of our improved machine for removing contents of paper cupsv and showing. the parts when in its normal and stationary position and a dotted position of the operating handle in its extreme upper position and also a dotted paper cup and its contents at the. position corresponding to said raised handle. Fig. 2 is a vertical side elevation of our machine, showing the carrier ring in section online 2-2 of Fig.

side View of means for holding an elastic stop. Figs. 8 and 9 are plan and elevation of the elastic stop.

In the figures,;1 1S one-half of the'frame of the machine and which is joined on line 3 to the second'half 2 of thema'chine; The contact line 3 of Figs. 3, 4 and 5, shows as a narrow contact surface in Fig. 2 and extends over the top of the machine and down the back to thejsurface 48 and also verticaL ly at the backof'the gear teeth'42 of the rack 17 and around the boss'43, leaving an Open slot in the front in which the flange 28 can travel. The main body of themachine has vertical parallel sides and the two halves 1 and 2 are held together by'the. screws 4 and 4 which project through the half 2 and screw-into the bosses 5 and 5 in the half 1. "6 and 7 are parallel sides of the frame 1 and 2 between which is housed the sector 8 with gear teeth 41 and having a shaft 9 jour11alled in thebearing .10.

handle 11 is fastened on said shaft 9 by means of a set screw'12. 13 is a grip at tachedto the end of handle 11 by being loosly'mounted on stud 14 and retainedby means-ofwasher15 and scr.ew16.. Handle 11 is curved as shown in Fig. lftoclear the c o1 1nter. 51 when in its normal bottom positionand offset sideways as shown in Figs. 3, 4 and-5 to avoid the ring 29 with plenty Slidably 'HlQilDlkd between guides. 18 and '19 formed in the frames halves land 2 is a rack 17 having teeth 42 which mesh with end of the groove guides 18 and 19 forms a stop of the rack 17 when it isQat the upper end of. its travel. The rack 17 asshown in Fig. 2 is in its normal position at rest at the bottom of its travel and in this position rests. on abumper or stop- 24 whichis, preferably made of a piece of rubberandformed in an inverted V shape as shown in detailin Figs. 8 and 9. '25 is a plate for supportin the stop 24, formed as shown in detail in igs fi and 7 andhelrl in a groove 26 (Figs. 2 and 3). The bumper 24 being made of rubber and formed of two parts meeting at an angle to make an inverted V shape as shown has the double resiliency of springing of the parts to recover its form and the springing of the rubber to recover its shape;

Fastened to the bottom of the front surface of the rack 17 by means of screws 27, 27 is a vertical flange 28 which has a horizontal ring portion 29 extending at right angles to said flange 28. The body halves 1 and 2 are spaced apart at their front verti -al surface to leave an opening 52 through which the tlange 28 projects and in which it can travel up and down. Ring 29 has an opening El) above which is a surface 31 for holding an inverted paper cup 32. The surface 31 is below the top surface of the ring 29 and connected to it by a suitable inclined surface which assi ts in center- .ing the cup over the opening 39. For conveiiience is then called a groove for holding a cup 32 33 is the bottom of the paper cup 32 and is turned up at the edge and of such a size and shape as to be pressed and held in position, as shown, by friction. The groove 34 in the opening or top of the cup 32 is for the purpose of holding a paper cover (not shown) which is pressed into position when the cup 32 is filled and can be easily removed by the fingers before placing the cup in our machine for pressing out its contents. 7

36 is a disk held stationary and in a position central over the opening 30 of ring 29 by means of arod 37 mounted in a boss 38 on the arm 39 which latter is attached to the frame parts 1 and 2 at their top. The arm 39 and boss 38 is formed in halves, one half being fastened to frame part 1 and one half being fastened to the frame part 2 and being in contact on the surface line 3. The rod 37 is fastened to the boss 38 by means of a pin 40.

43 is a hollow boss with a brace 44 on each part of the halves 1 and 2, one half of 453 on frame part 1 and one half on frame part 2 and matched to hold a nut 47 through which a thumb screw 45 passes. On the upper end of thumb screw 45 is revolvably held a disk 46 between which and the horizontal surface 48 may be clamped the horizontal top of a counter or table 51 (shown dotted) for firmly holding the machine in an upright position as shown in Figs. 1, 2 and In Fig. 1, 11 shows handle 11 raised to its extreme upper position when the ring 29 is in a position 29 and the paper cup 32 is in the position 32. The bottom 33 of the cup 32 will then be at 33 while the contents of the cup will be at 49 on the plate 50.

The operation of the machine is as follows: A paper cup 32 tilled with ice cream. has its cover removed from the groove 34 and is then inverted and placed in the groove 35 on the ring 29 as shown in Fig. ()perati-n-g the handle 11 to a position 11. (Fig. 1) raises the ring 29 to a position 29 through the medium of the sector 8 and rack 17 (Fig. 2). lVhen the bottom of the paper cup 32 contacts with the disk 36 it is in the position 33 where it remains while the cup 32 continues up to the position 82 forcing it away from its contents which is left at 49 on a plate 50. The plate 50 is placed beneath the ring 29 and car ried up with it by hand to receive the ice cream 49 as it passes through the opening :30 of said. ring 29. The cup 32 is preferably larger at its open top and tapers towards its bottom so its contents when loosened from the inside of the eup 32 readily passes through its top. When the plate 50 with its ice cream 49 and cup bottom 33 is removed from the machine a cup bottom 33 is lifted off. The handle 11 is then released and is returned to its normal position at 11 by the weight of a ring 29, rack 17 and its own weight after it passes over the center of the shaft 9. f
